If you need parts to build up that shiny new AR lower you just received, look to our Lower Parts Kit (less the trigger group). It is perfect for the individual who already has the most common upgrades for an AR15 such as an upgraded grip, trigger guard and trigger group. Even if you already have an assembled lower, keep a few of our kits around for spare parts because our kits are set at factory direct prices.

For gunsmiths, we offer PRO kits of our springs, pins and detents. This is perfect for keeping on hand for those days when you accidentally shoot a pivot pin detent across the room into an abyss of carpet during your installations.
